[rules-users] Using count()

[Mark Proctor]

look at hte Shopping Example, I use sum() there, but the concept is the 
same:

rule "determine 10% discount if total purcahses is over 100"           
    no-loop true   
    when
        $c : Customer()
        $i : Double(doubleValue  > 100) from accumulate ( Purchase( 
customer == $c, $price : product.price ),
                                                                    sum( 
$price ) )
    then
          $c.setDiscount( 10 );
        insertLogical( new Discount($c, 10) );   
end
